View in. front elevation, partly broken away, ol." the upper portionol.' a Storage hatN tery cell, allowing in section, a slightly modi--lied torni of my invention applied thereto.

Referring to the drawing', reference enaractor l represents a cellcontainer or battery can havingl therein a Suitable electrolyte 2 andbattery elements having; lpoles 3 and 3l., whieh pass; through suitableinsulating stalling boxes in the top of the container, all as is usualwith devices of this character. Threaded through the top of thecontainer' l and preferably through a reinforcingr sleeve 4l fixed tothe top of the container is the filtering aire l particularly formingthe subject matter of my invention. This valve eonipries a pair ofnested tubes, the outer tube 5 oiE which is suitably threaded forengagement with 'the sleeve il and is preferably maintained in fluidtight engagement'therewith by means of a gasket (l. The inner end ol thebore 7 of this tube is preferably eonetrieted to forni a lower outletopening 8 relatively small in cross sootional area compared with that olthe inain portion of the bore, and the oppoaite ond portion o'll thebore is enlarged to lorni a shouldered Seat f). This tube has apluralityv et ventey l0 'ereunrterentially arranged in the side thereofand positioned slightly above the lower outlet opening! S, thus placingthe niai'n portion ot the bore in direct Conununie: tion with theinterior ot the container l. The inner and relatively short tube 1l isspaced `from the sidra of the bore tion ol whieh constitutes the "alveSeat thereior. "ho enlarged end portion ot the bore 'r isi closed bymeans ot a, :ap 16 threaded therein and which bear-S upon a, gasket 17which locks the Flange '13 on its seat and provides means vfor limiting'the lateral movement ol the puppet valve 15. The cap 16 has; apassageway 1S therethrough permitting the escape o'l" the gases' afterthey have paaeed'tho puppet valve. The nap 1G 1s prellerably providedwith an inwardly extending projection 25, arranged abstain tiallycentrally thereof and through which the passageway 1S preferablyextends; this projection 25 serving as lneans for limiting n theembodiment illustrated in Fig. 2, a baiile plate 22, preferably in theform of a segment of a sphere, is attached to the lower end of each ofthe tubes 5 and 11, in spaced relation thereto, by .means ofspaced arms23,

with the convex side of each plate 22 up'- wardly disposed. The bailleplate attached to tube 11 is preferably positioned above the openings 10in the outer tube 5 so as to intercept any liquid which may splashthrough these openings. j l

In operation, the liquid-saturated gases within the container 1 passthrough the vents 1 0 which act to separate the liquids from the gases,the liquids passing back into the container through the open end 8 oftube 5 While the partly filtered gases pass up through the bore 7 andthrough the vents 14. The obstruction of the outlet openings 8 and 12 bythe liquids in returning to the body of electrolyte 2 tends to cause thegases to pass through. the vents 1Q and 14. The movement of the gasesthrough the second set of vents Y aga-in separates them from theircontained liquids and this filteringl operation may be continued asdesired, it merely being necessary'to install a sulticient number ofnested tubes to insure 'a substantially thorough filtration orseparation of all of the liquids f rom the gases before they are'.,finally' permitted to' escape. The arrangement of the outlet openingsSaand 12 substantially in vertical alinement with each other, as shown,facilitates the return of the filtered liquid directly vto theelectrolyte 2. The puppet valve 15 normally maintains the interior ofthe container out of communication with the outside air, but this puppetvalve may be made as light as desired so that but little internalpressure is necessary to move this valve into open positionand therebyeliminate the possibility of the generation of an abnormal pressurewithin the container. In the embodiment' illustrated in Fig. 2, thebatilc lplates 22 tend to prevent the splashing of any of theelectrolyte into the bores of tubes 5 andll respectively, but permit theready return of any liquid in these tubes to the body of electrolyte 2in the container 1.

' Accordingly, it is preferable to employ the form shown in Wig. 2 inbattery cells which will be subjected to shocks and jars, as in the caseof-cells used on vehicles.

It will be apparent from this .disclosure that the diierent parts of myinvention may be cheaply manufactured and readily assembled and takenapart for the repair and substitution of parts.
